Lightly brush one corn tortilla with oil and then sprinkle with sea salt. Repeat with remaining tortillas, stacking them as you finish brushing each one. If you want really symmetrical tortilla chips, cut the pile of oiled tortillas (first in half, then in half again etc., until you have triangle shaped chips). Place brushed tortilla pieces in a jelly roll pan. Bake 350 degrees for about 20 minutes. Check periodically for desired crispness.

Optionally, instead of cutting wedges out of the tortilla stack, you can lay each brushed tortilla on the baking sheet and bake as above. When they're done to your liking, you can break the tortillas into smaller pieces.
